Benefits of technology

The present invention is a vehicle control system for autonomous driving that can reliably alert the surrounding vehicles and pedestrians when the driver becomes unable to drive. This helps to improve safety and minimize unnecessary alarming of surrounding people. Additionally, the system uses a single light source for both warning and signaling, reducing the number of light sources needed. The driver's health and urgency of the situation are also considered, with the system restricting unnecessary switching of the lighting mode to prevent alarming the surrounding people. Overall, the invention provides an effective solution for ensuring safe autonomous driving.

Problems solved by technology

Therefore, simply turning on the headlight may not properly warn the surrounding vehicles and pedestrians of the occurrence of an emergency situation.

second embodiment

[0104]The mode of operation and advantages of the vehicle control system 101 of the second embodiment are discussed in the following.

[0105]In the vehicle control system 101 of the second embodiment, when the headlight 14e is periodically switched between the first state and the second state in the lighted state of the headlight 14e, all of the second light sources 162e included in the second light source group 162 are turned on and off while all of the first light sources 161e included in the first light source group 161 are kept turned on.

[0106]Therefore, the first light sources 161e of the headlight 14e continue to be turned on while the switching of the lighting mode is being executed. The first light sources 161e may each consist of a light source such as an HID lamp that requires a certain time period to be fully bright after being turned on.

[0107]The vehicle control system 201 according to a third embodiment of the present invention switches the direction of the light source o...

first embodiment

[0108]The headlight 14e is not provided with light sources corresponding to those of the first light source group 61 in the previous embodiment, and consists solely of a second light source group 262 which includes at least a pair of second light sources 262e provided on either side of the front end of the vehicle. The second light sources 262e may be supported at the front end of the vehicle body so as to be tiltable (rotatable) around a laterally extending rotational axis. Thus, the second light sources 262e are moveable between a first state in which the irradiation direction is slightly downward with respect to the horizontal direction, and a second state in which the irradiation direction is slightly more upward than in the first state. The irradiation distances in the first state and the second state may be similarly determined as in the The second light sources 262e may each consist of an LED light, a HID lamp, or a halogen lamp.

[0109]The external notification control unit 6...

third embodiment

[0110]The mode of operation and the advantages of the vehicle control system 201 of the third embodiment are discussed in the following.

[0111]In the vehicle control system 201 according to the third embodiment, the headlight 14e is periodically switched between the first state and the second state by changing the irradiation direction while the second light sources 262e are kept turned on.

[0112]Since the switching is performed by changing the irradiation direction, the second light sources 262e are not required to be turned off. Therefore, a light source that has high luminance but requires a long time before lighting can be used as the second light sources 262e. Such light sources may be capable of producing a high intensity light with a relatively small power consumption so that the switching of the lighting mode of the headlight 14e is easily recognized by pedestrians and occupants of surrounding vehicles.

[0113]The vehicle control system 301 according to a fourth embodiment of th...

Abstract

In a vehicle control system (1, 101, 201) configured for autonomous driving, and having a control unit configured to execute a stop process by which the vehicle is parked in a prescribed stop area when it is detected that the control unit or a driver has become incapable of properly maintaining a traveling state of the vehicle comprising, an external notification unit (14) includes a headlight, and the control unit is configured to change a lighting mode of the headlight in a repetitive manner in the stop process.

Description

TECHNICAL FIELD[0001]The present invention relates to a vehicle control system configured for autonomous driving.BACKGROUND ART[0002]According to a known travel control system that autonomously drives the vehicle to a suitable stop position and park the vehicle at the stop position when the driver is detected to be unable to continue to properly drive the vehicle. See JP2016-196285A, for example. According to this prior art, when the vehicle is being autonomously driven to the stop position, the headlight is turned on so as to warn the surrounding vehicles of the occurrence of an emergency situation.[0003]The headlight is used whenever the vehicle is traveling at night or in a dark condition. Therefore, simply turning on the headlight may not properly warn the surrounding vehicles and pedestrians of the occurrence of an emergency situation.SUMMARY OF THE INVENTION[0004]In view of such a problem of the prior art, a primary object of the present invention is to provide a vehicle contr...
